PUBLISHED APRIL 29, 1969 650,439 FABRIC SURFACED HYDROCARBON RUBBER LAMlIENATE AND PROCESS OF PREPARING SAM Kenneth Vincent Martin, Newark, Del., assiguor to E. I. du Pont de Nemours and Company, Wilmington, Del., a corporation of Delaware Filed June 30, 1967. Published Apr. 29, 1969 Int. Cl. D06n 3/10, 7/06 US. Cl. 161-96 1 Sheet Drawing. 7 Pages Specification A laminated element comprising a vulcanized hydrocarbon rubber slab having a textile fabric partially embedded in at least one surface. The laminated element is prepared by vulcanizing a slab of EPDM rubber, styrene/butadiene rubber or neoprene having a woven or nonwoven fabric partially embedded in one surface. This element can be bonded to a rigid member by applying an adhesive to the fabric and laminating the element to the rigid member. Useable adhesives are molten asphalt or neoprene contact cement.

In an alternative embodiment, a second layer of fabric may be fully embedded in the body of the rubber slab. This aids in counteracting any tendency of the surface layer of the fabric to curl the rubber slab.

The laminated element of this invention can be used as the running surface or the resilient base of a race track or an athletic field. Other uses include preparation of gym floors, sidewalks or basements.
